This application is a continuation-in-part of U.S. application Ser. No. 29/525,606, filed Apr. 30, 2015, the entirety of which is incorporated by reference.

FIELD OF THE INVENTION

The present invention relates generally to wireless audio communications, and more particularly relates to a device, system, and method for synchronously sharing music content from an audio output device to a plurality of audio receiver devices over a wireless network.

BACKGROUND OF THE INVENTION

People desire the ability to simultaneously listen to music. Unfortunately, existing technologies for doing so are limited. For example, one common method for multiple individuals at remote locations to simultaneously listen to music is to tune-in to the same radio broadcast station that broadcasts music on predetermined FM/AM/satellite channels. Unfortunately, radio station broadcasts are restricted to listening to the radio station's selection of music, which may not be desirable. Additionally, many people do not have immediate access to FM/AM/satellite radio station tuners/receivers, except when they are in their vehicles. Some individuals prefer listening to online music services, such as Pandora, that can be listened to on their mobile devices and that provide individualized music content that can be dynamically tailored to the individual's musical tastes. Some online music services can develop a personal radio station for each user that is particularly tailored, over time, to the individual's unique musical tastes, through the individual's feedback on streamed songs and other personal criteria.

In this era of social networking, an individual's real-world and social network “friends” or followers may desire the ability to listen to the individual's personal radio station, as a way of personally connecting with the individual. The individual's real-world and social network friends or followers may also desire the ability to simultaneously listen to whatever music content the individual may be currently listening to on his/her mobile music device. This may be achieved by, for example, receiving streamed music through an online music service or listening to music files stored on the individual's mobile music device. One can imagine that if the individual were a celebrity, or other personality with a large volume of followers, this ability to simultaneously share music content with the individual would be highly coveted. Unfortunately, existing technologies for doing so are lacking.

One popular device for listening to music is a cellular mobile device, or smartphone, which individuals usually carry with them on their person, or in very close proximity, at most times. Existing technologies for simultaneously sharing, in real-time, an audio signal on one personal cellular mobile device with multiple individuals include using the cellular mobile device's speaker to broadcast the audio signal to anyone within listening range. This method only works for simultaneously sharing audio content with individuals that are in close proximity to the cellular mobile device's speaker. Furthermore, the audio content is shared with anyone within listening distance, rather than to a selected group of individuals who desire the ability to listen to the audio content. Another method of simultaneously sharing audio content from one personal cellular mobile device with multiple individuals is plugging a headphone set into an audio output port on the cellular mobile device with multiple pairs of earbuds. This allows multiple listeners to listen to the same audio content, via the earbuds, without broadcasting the audio to unwanted listeners who may also be in the listening vicinity. Unfortunately, this method only allows sharing of audio content with listeners who are in close proximity to the cellular mobile device. In other words, it limits sharing of the audio content to a range associated with the length of the physical wire of the headphone set. Sharing music being played on the cellular mobile device simultaneously to remotely located listeners is not possible with such existing methods.

Another existing technology for sharing music content playing on a personal mobile device with multiple listeners is to pair multiple Bluetooth-enabled headsets with the mobile device and communicate the audio content to each of the headsets via a Bluetooth piconet. Unfortunately, this method is limited to short range wireless communications because Bluetooth communications are limited to a range on the order of meters or less. For example, Bluetooth typically operates within a range of less than ten meters. In addition, Bluetooth networks are limited to seven active devices. More particularly, current Bluetooth protocol allows only one audio receiver slave device, e.g. headset, to be paired to a master device, e.g. cellular mobile phone, at a time. Also, Bluetooth communications have a relatively small data transfer rate of up to approximately 3 Mbps, as compared with other wireless communication protocols, e.g., Wi-fi, which can have data transfer rates of 30 Mbps. Higher data transfer rates can amount to higher sound quality and sharing with more receiver devices.

Another popular method of simultaneously sharing music content is live musical concerts. One of the drawbacks of sharing a musical experience at a live musical concert is that concerts are limited to a predetermined venue and a very limited predetermined time period. Additionally, concert tickets can be relatively expensive and because concerts normally take place at a single venue location, it is not always possible for fans to attend the concert because it is being held too far away. Therefore, what is desired is a device, system, or method that allows audio content from a single music content source, e.g., a cellular mobile device or a speaker at a music concert, to be simultaneously, synchronously communicated, over long distances, to a multitude of remote audio receiver devices. Unfortunately, simultaneously sharing music over long distances presents many technical challenges including establishing high sound quality and secure long range communications, while also communicating data relatively quickly and compensating for propagation delay of the music content from the source transmitting device to the multitude of destination receiver devices.

Further, music content, e.g. a song, is often copyright protected. Therefore, permissions to share the music content should be carefully managed with any music sharing technology to ensure compliance with intellectual property rights.

Therefore, a need exists to overcome the problems with the prior art as discussed above.

DETAILED DESCRIPTION

While the specification concludes with claims defining the features of the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the following description in conjunction with the drawing figures, in which like reference numerals are carried forward. It is to be understood that the disclosed embodiments are merely exemplary of the invention, which can be embodied in various forms.

The present invention provides, in accordance with one embodiment, a novel and efficient portable wireless plug-in repeater that plugs into an audio output of an audio processing device. The repeater is able to synchronously share music from the audio output of the audio processing device with at least one remote audio receiving device over a wireless network. Embodiments of the invention provide for a portable wireless plug-in repeater that allows for secure synchronous sharing of music files over a long range wireless communications channel to a plurality of remote audio receiving devices. In addition, embodiments of the invention provide for a plug-in repeater having a housing enclosing various electronic components, including a processor, a wireless network interface with an antenna, a user-input interface, a display, a processor, a USB port, and an analog to digital converter (ADC). In one embodiment, the audio plug protrudes outwardly from an external surface on the housing so as to be insertable within a standard audio jack, or audio output port of a portable electronic device, such as a cellular communication device. In a further embodiment, analog signals transmitted via the standard audio jack and received by the audio plug are converted to digital audio signals by an analog to digital converter (“ADC”). The converted digital audio signals may then be encrypted and transmitted via the antenna over a network capable of long range communications, such as a Wi-fi network. The term “Wi-fi” refers to a wireless local area network (WLAN) that uses the IEEE 802.11 protocol standard. As is known in the art, Wi-fi technology is often used to provide Internet access to devices within the range of the Wi-fi WLAN, which is usually provided by an access point, such as a Wi-fi router. Wi-fi also allows for direct computer-to-computer communications via a peer-to-peer ad hoc network for short range communications. In alternative embodiments, the converted audio signal can be transmitted to remote audio output devices through other wireless network protocols.

In further embodiments, the plug-in repeater can be plugged into audio output devices other than a cellular mobile phone, e.g. a speaker, a headset, etc. Advantageously, any analog audio output from a standard audio jack, or audio output port can be received by the plug-in repeater and then synchronously shared with remote audio receiver devices over a wireless network.

Some embodiments of the invention include a particular social networking aspect. For example, the processor on the plug-in repeater can execute computer instructions for communicating with a remote music sharing server system that manages the social networking aspect of the present invention. More particularly, the remote music sharing server system can include a database that stores music files of the social network's users and each user's associated listening permissions. In some embodiments, the music files can be associated with a third-party music server system, e.g. iTunes, which has granted licenses to users to download and listen to the music files. An indication of such legal permissions may be stored in the database and associated with each music file so that only users with legal permission may listen to the music file and any “friends” who desire to share the music content may only listen to the music files simultaneously with the user having legal permission to listen to the music file. In addition, the database can store identification information for users' audio output devices, which are registered with the remote music sharing server system and can be used by the remote music sharing server system to identify, locate, and remotely synchronously share music content with said audio output devices. Users associated with the remote music sharing server system may, in some embodiments, be able to view and access their friends' audio output devices in order to initiate synchronously sharing music content to selected audio output devices. Accordingly, the present invention provides a social networking platform with a music sharing server system in wireless communication with plug-in repeaters and other audio input/output devices that allows users to leverage their friends' music content permissions to listen to music with their friends' in a synchronous/simultaneous manner over long range wireless communications networks. In one embodiment, a software application may be provided to allow a friend to purchase a license (and/or download the song) in order to be able to listen to the song independently from his/her friend, or otherwise have legal permission to listen to the song independently. Accordingly, music companies may obtain additional profits from such music purchases. Although the following description will focus primarily on long range wireless communications, it is understood that the synchronous sharing of music content may, in some embodiments, occur over short range wireless communications, as well as, wired communications. In addition, although the description below discusses “music content” and “songs,” it is understood that, in some embodiments, the synchronously shared content may include other audio content, such as voice, or may include other media content, such as, for example, video content.

Referring now to FIG. 1, one embodiment of the present invention is shown in a perspective view. FIG. 1 shows several advantageous features of the present invention, but, as will be described below, the invention can be provided in several shapes, sizes, combinations of features and components, and varying numbers and functions of the components. The first example of a wireless plug-in repeater 100, as shown in FIG. 1, includes a body 102 having a housing 104 and an audio plug 106 protruding from an exterior surface of the housing 104.

In one embodiment, the housing 104 defines an interior area where a plurality of electronic components are disposed, which electronic components will be described in more detail below, with reference to FIG. 3. In a preferred embodiment, the wireless plug-in repeater 100 is sized and configured as a portable wireless plug-in repeater 100 that couples to a mobile device, such as a smartphone, such that the housing 104 has a smaller overall surface area than a standard-sized smartphone (see. FIG. 2). Accordingly, coupling the wireless plug-in repeater 100 to a standard-sized smartphone may not inconvenience users that are accustomed to the relatively small and portable form factor of such handheld devices. Although the device 100 is referred to herein as a “repeater,” it is in no way limited to only repeating audio or other data. The term “repeater” is only being used to simplify the instant discussion of certain embodiments and, as will be explained later, the device 100 is capable of generating its own content and receiving signals, data, and other information from the devices it transmits to.

In one embodiment, the housing 104 may include a width that is equal to or less than a width of a standard-sized smartphone. In another embodiment, the housing 104 may include a width that is only slightly wider than the width of a standard-sized smartphone. In yet another embodiment, the housing 104 includes a length that is less than a length of a standard-sized smartphone. In a further embodiment, the housing 104 includes a length that is less than one-half the length of the standard-sized smartphone. In yet a further embodiment, the housing 104 may include dimensions outside of these ranges. Although the housing 104 is depicted as rectangular-shaped with rounded corner edges, it is understood that, in some embodiments, the housing 104 may be formed as other shapes, sizes, and configurations. In one embodiment, the wireless plug-in repeater 100 may be non-portable. In other words, the wireless plug-in repeater 100 may be larger than the standard-sized smartphone. In another embodiment, the wireless plug-in repeater 100 may be sized and configured to couple to devices substantially smaller than the standard-sized smartphone (e.g., a smart watch).

In one embodiment, the housing 104 at least partially defines a USB port (not shown) or other data input/output port for communicatively coupling the wireless plug-in repeater 100 to a computing device (e.g. personal computer). Coupling the wireless plug-in repeater 100 to the computing device may allow the user to initially register the repeater 100 with a music sharing server system associated with the social networking aspect of the present invention. In a further embodiment, the USB port or other data input/output port may be used to obtain large volumes of music content from the computing device during the initial registration phase in order to transfer or copy the music content to the music sharing server system. This would allow for remote distribution of the music content to a plurality of audio receiver devices, from the music sharing server system, during synchronous music content sharing sessions, in accordance with some embodiments of the present invention. In addition, authentication and security protocols may be established during this initial registration phase. In one embodiment, the USB port may be used by the user to plug-in a USB headset for listening to the music content from the wireless plug-in repeater 100. Alternatively, the user may listen to the music content via another wired or wireless connection, such as, a Bluetooth headset.

In one embodiment, the housing 104 may include a computer display 108. In another embodiment, the computer display 108 may be configured as a touchscreen for allowing a user to input commands that are received by the electronic components within the interior area of the housing 104. The computer display 108 can be any type of suitable display, such as a liquid-crystal display (LCD), a plasma display, a light-emitting diode (LED) display, or the like, that may be used to present various images, text, graphics, icons, or videos to the user. The computer display 108 may display a keypad (not shown) that may include alphanumeric keys for allowing entry of alphanumeric information (e.g. log-in user names and passwords, contact information, text, etc.). The touchscreen may also provide output or feedback to the user, such as haptic feedback or orientation adjustments of the keypad according to sensor signals received by motion detectors, such as an accelerometer, located within the wireless plug-in repeater 100. The computer display 108 may display information to the user such as an operating state, time, various menus, application icons, pull-down menus, input fields, music content titles, artists, albums, etc., and the like.

In one embodiment, the computer display 108 may be configured to display a software application interface for the social networking aspect of the present invention, discussed in more detail herein below. Advantageously, because the software application is configured for execution on the wireless plug-in repeater 100, rather than a smartphone, the software application need not be purchased or otherwise acquired or downloaded with any fees or restrictions associated with the smartphone, or smartphone manufacturer. It is known that some smartphone manufacturers, e.g., APPLE, require that users download and purchase software applications configured for execution on a mobile device (e.g., tablet or smartphone), i.e, “apps,” through proprietary software applications and systems. Further, app developers are required to develop the apps through proprietary systems and protocols, which can increase the costs of app development and ultimately affect end user purchase prices and profit margins for app developers. In a further embodiment, the wireless plug-in repeater 100 may not include a software application or the computer display 108. In this embodiment, user inputs and outputs may be provided through other configurations, components, or peripheral devices.

In one embodiment, the audio plug 106 includes a first end 110 and a second end 112 opposite the first end 110. The first end 110 may be coupled to and protrude outwardly from at least a portion of an external surface 114 of the housing 104. In one embodiment, the first end 110 is removeably couplable to the housing 104. This may be useful for embodiments that allow users to interchange audio plugs of varying sizes and configurations. In an alternative embodiment, the first end 110 is integral or unitary with the housing 104. In yet another embodiment, the first end 110 is coupled to the housing 104 so as to not be removable from the housing 104 without damaging the wireless plug-in repeater 100.

Referring still to FIG. 1 with reference to FIG. 2, in one embodiment, the second end 112 is disposed external to the housing 104. The second end 112 may include an external surface 116 defining at least one electrically conductive region operably configured to be insertable within an audio output port 200 of an audio output device 202 for receiving an analog signal from the audio output device 202. As used herein, the term “audio output device” is intended to indicate any device operable to output analog audio signals. In a preferred embodiment, the analog signal is an analog audio signal associated with a music content, such as a song or other musical composition. In another embodiment, the analog signal may be other analog signals, such as a microphone audio signal. The audio output device 202 may be a smartphone, a headset, a microphone headset, a speaker, a musical instrument, a computer tablet, a personal computer, or other computing device, and the like. The audio output port 200 may be an audio jack. Known jacks include single prong monoaural or stereo jack and double prong jacks. Most portable audio devices use 3.5 mm jacks, although smaller and larger jacks are known. For example, 2.5 mm jacks may be used in some embodiments and 6.35 mm jacks may be used by some audio output devices, such as home or professional audio output equipment.

Referring primarily to FIG. 3 with reference to FIG. 2, an exemplary jack-and-plug coupling is illustrated in a partial, enlarged cross-sectional view of FIG. 2. The audio plug 106 of the wireless plug-in repeater 100 is shown inserted within at least a portion of the audio output port 200 of the audio output device 202. In one embodiment, the audio plug 106 is electrically couplable to the audio output port 200 of the audio output device 202 for receiving from and, in some embodiments, transmitting signals to the audio output device 202. The audio output device 202 may include a digital-to-analog converter (DAC) for converting digital signals from a processor within the device 202 into analog signals that can be output via the audio output port 200. In one embodiment, the DAC may provide left and right analog audio signals to the audio output port 200 for stereo audio communications. In a further embodiment, the audio output device 202 may also include an analog-to-digital converter (ADC) for converting analog signals (e.g., microphone audio signals) received via the audio output port 200 into digital signals that can be communicated to the processor within the device 202. In yet a further embodiment, the analog signal may be a microphone analog signal.

In one embodiment, the audio output port 200 is configured to receive an audio plug 106 of a predetermined length, diameter, and electrical configuration. For example, the audio output port 200 may include four electrically conductive terminals 300, 302, 304, and 306 at predetermined positions within the audio output port 200. The terminals 300, 302, 304, and 306 may be configured to electrically couple with predetermined electrically conductive regions 308, 310, 312, and 314 on the audio plug 106. In one embodiment, the electrically conductive regions 308, 310, 312, and 314 may be separated by electrically isolating regions 316, 318, and 320. In another embodiment, for stereo communications, regions 308 and 310 may be dedicated to left and right audio signals and regions 312 and 314 may be dedicated to ground. In yet another embodiment, for non-stereo communications, region 308 may be dedicated to audio speaker signals; regions 310 and 312 may be for ground; and region 314 may be for a microphone signal. In one embodiment, the audio output port 200 may include three electrically conductive terminals for coupling with an audio plug 106 having three electrically conductive regions. In yet other embodiments, the audio output port 200 may include more than four or less than three electrically conductive terminals. In a further embodiment, the audio plug 106 may include more than four or less than three electrically conductive regions. In a preferred embodiment, the audio plug 106 is a 3.5 mm audio plug with four electrically conductive regions separated by three electrically isolating regions.

Referring now to FIG. 4, an exemplary embodiment of the wireless plug-in repeater 100 is illustrated in a block diagram. In one embodiment, the wireless plug-in repeater 100 includes a wireless network interface 400, a processor 402, a memory 404, a display 406, a user input interface 408, an amplifier 410, a speaker 412, a digital data port 414, and the audio plug 106.

In one embodiment, the wireless network interface 400 may include one or more network interface cards (NIC) or a network controller. The wireless network interface 400 can be hardware and/or a computer program that is responsible for wireless communications. The wireless network interface 400 may include an antenna 416. In one embodiment, the antenna 416 is a radio frequency transmitter and/or receiver for transmitting and receiving radio frequency signals. In another embodiment, the antenna 416 is a radio frequency transceiver. In one embodiment, the analog audio signals received via the audio plug 106 are converted into digital signals by an ADC and subsequently transmitted wirelessly via the antenna 416 over a wireless network. Although the wireless network interface 400 is discussed as providing for wireless communications, in some embodiments, the wireless network interface 400 may also include hardware and/or software components configured to provide wired communications.

In some embodiments, the wireless network interface 400 may include a personal area network (PAN) interface. The PAN interface may provide the capability for the wireless plug-in repeater 100 to network using a short-range communication protocol, for example, a Bluetooth communication protocol. Bluetooth is an industrial specification for wireless PANs. Bluetooth provides a way to connect and exchange information between devices such as smartphones, laptops, PCs, printers, digital cameras, and video game consoles via an unlicensed, short range radio frequency. Bluetooth typically operates at a frequency of about 2.4 GHz. In order to use Bluetooth wireless technology, a device must be able to interpret certain predefined Bluetooth profiles. The profiles define the possible applications that work with the device. Bluetooth profiles define general behaviors through which Bluetooth-enabled devices communicate with other devices. Bluetooth technology defines a wide range of profiles that describe many different types of use cases. At a minimum, each profile specification contains information on the following topics: dependencies on other profiles; suggested user interface formats; and specific parts of the Bluetooth protocol stack used by the profile. To perform its task, each profile uses particular options and parameters at each layer of the stack. The configuration information regarding a profile is in the upper layers of a Bluetooth stack, typically an application layer. The proper profile for a device must be used to establish communication with the device. Beyond those profiles typically needed for general operation, well over twenty device class profiles currently exist. For example, Advanced Audio Distribution Profile (A2DP) is designed to transfer a 2-channel stereo audio stream, like music from an MP3 player, to a headset or car radio. The Headset Profile (HSP) is the most commonly used profile, providing support for Bluetooth headsets to be used with smartphones. It provides for audio communications and relies on a subset of commands to provide minimal controls, including the ability to ring, answer a call, hang up and adjust volume. Other profiles exist for operations, such as, for example printing, transferring files, and video streaming.

In one embodiment, the PAN interface may permit the wireless plug-in repeater 100 to connect wirelessly to another electronic device (e.g., an audio receiver device) via a peer-to-peer, ad hoc connection. For example, in one embodiment, the wireless network interface 400 may include a Wi-fi interface that is configured to support short range, peer-to-peer ad hoc communications. Ad hoc networks allow devices to communicate directly with each other in a peer-to-peer configuration, without requiring an access point, such as a Wi-fi router.

The wireless network interface 400 may also include a local area network (LAN) interface. The LAN interface may be, for example, an interface to a wireless LAN, such as a Wi-fi network. In one embodiment, there is a wireless LAN located at or near the wireless plug-in repeater 100 that provides the wireless plug-in repeater 100 with access to the Internet for communicating with the music sharing server system to manage long range communications, such as synchronously sharing music content over long distances and sending and receiving identification, authentication, timing, and control commands in accordance with the present invention. The range of the LAN interface may generally exceed the range available via the PAN interface. Typically, a connection between two electronic devices via the LAN interface may involve communication through a network router or other intermediary device. More particularly, the wireless network interface 400 may include the capability to connect to a wide area network (WAN), such as the Internet, via an access point, such as a Wi-fi network router associated with a wireless LAN. Because the wireless plug-in repeater 100 is intended for connection to a multitude of devices via the audio plug 106, including a smartphone, the wireless plug-in repeater 100 may not include a cellular mobile communications network interface.

The wireless network interface 400 preferably includes a Wi-fi interface, or IEEE 802.11. In one embodiment, the wireless network interface 400 includes a Wi-fi modem for wirelessly connecting to a Wi-fi access point (AP) that may be considered a router, a gateway, or a hotspot. Currently, APs have a range of about 20 meters indoors and an even longer range outdoors. Wi-fi networks are generally considered less secure than its wired counterpart, Ethernet communications, or Bluetooth networks. On the other hand, Wi-fi networks are able to connect to more devices than Bluetooth networks and offer a much longer range of wireless communications than Bluetooth.

In one embodiment, the wireless plug-in repeater 100 may also include a near field communication (NFC) interface. The NFC interface may allow for extremely close range communication at relatively low data rates (e.g., 424 kb/s). The NFC interface may take place via magnetic field induction, allowing the NFC interface to communicate with other NFC interfaces located on other electronic mobile devices. The NFC interface may enable initiation and/or facilitation of data transfer from the wireless plug-in repeater 100 to another electronic device with an extremely close range (e.g. 4 centimeters).

The processor 402 can be, for example, a central processing unit (CPU), a microcontroller, or a microprocessing device, including a “general purpose” microprocessing device or a special purpose microprocessing device. The processor 402 executes code stored in the memory 404 in order to carry out operation/instructions of the wireless plug-in repeater 100. The processor 402 may provide the processing capability to execute an operating system, run one or more applications, and provide processing for one or more of the techniques described herein.

In one embodiment, the processor 402 includes an ADC and/or a DAC 418. Although the ADC/DAC unit 418 is depicted as part of the processor 402 in FIG. 4, it is understood that, in other embodiments, the ADC/DAC 418 may be separate from and communicatively coupled to the processor 402. For example, in an alternative embodiment, the ADC/DAC 418 may be communicatively coupled between the processor 402 and the audio plug 106. Further, the ADC/DAC 418 may be implemented as a single unit in some embodiments, or as separate ADC and DAC components in other embodiments. In one embodiment, the ADC is operable to convert analog data into digital data at a rate of approximately 192 kHz, which is approximately five times the resolution of a typical music CD. Advantageously, providing an ADC that is able to convert analog into digital at a relatively high rate, as compared with other methods, provides a higher quality musical sound. In another embodiment, the ADC may be operable to convert analog data into digital data at rates higher than or less than 192 kHz.

In a further embodiment, the wireless plug-in repeater 100 may include an encryption module 420. The encryption module 420 may be included in the processor 402, or may be communicatively coupled to and separate from the processor 402. The encryption module 420 may be a software program configured to apply one or more encryption techniques to the analog audio signals received via the audio plug 106, or other data. In yet a further embodiment, the analog audio signals are converted into digital signals by the ADC/DAC 418 prior to applying the one or more encryption techniques. Because Wi-fi networks are considered less secure than Bluetooth networks, the encryption module 420 may be provided as an additional layer of security for wireless communications over the Wi-fi network. In one embodiment, the processor 402 is a high-speed processor. The processor 402 is preferably a relatively high-speed processor in order to process a high rate of analog-to-digital conversion for high sound quality and for applying the encryption techniques to the data.

The memory 404 associated with the wireless plug-in repeater 100 may be, for example, one or more buffer, a flash memory, or non-volatile memory, such as random access memory (RAM). The wireless plug-in repeater 100 may also include non-volatile storage. The non-volatile storage may represent any suitable storage medium, such as a hard disk drive or non-volatile memory, such as flash memory or an EEPROM.

The display 406 displays information to the user such as an operating state, time, various menus, icons, pull-down menus, application interfaces, and the like. The display 406 may be used to present various images, text, graphics, icons, or videos to the user. The display 406 may be any type of suitable display, such as a liquid-crystal display (LCD), a plasma display, a light-emitting diode (LED) display, or the like.

The user input interface 408 allows the user to provide inputs to the wireless plug-in repeater 100. The user input interface 408 may also facilitate interaction between the user and the repeater 100. The user input interface 408 may include a keypad providing a variety of user input operations. For example, the keypad may include alphanumeric keys for allowing entry of alphanumeric information (e.g. telephone numbers, contact information, text, etc.). The user input interface 408 may include special function keys (e.g. a volume control buttons, back buttons, home button, etc.), navigation and select keys, a pointing device, and the like. Keys, buttons, and/or keypads may be implemented as a touchscreen associated with the display 406. The touchscreen may also provide output or feedback to the user, such as haptic feedback or orientation adjustments of the keypad according to sensor signals received by motion detectors, such as an accelerometer, located within the repeater 100.

The wireless plug-in repeater 100 preferably provides the user with the capability of listening to the music content that is either received via the audio plug 106, or through another input, such as the wireless network interface 400 or the digital data port 414. Accordingly, in one embodiment, the wireless plug-in repeater 100 may include the amplifier 410. The amplifier 410 may be communicatively coupled to the speaker 412 for amplifying audio signals that are transmitted to the speaker 412. The speaker 412 uses the audio signals to cause vibrations that produce sounds waves. In other embodiments, the user may listen to the music content through other audio receiver devices, such as a USB headset or a Bluetooth headset.

The digital data port 414 functions to allow digital data to be communicated through a wired connection, which may be particularly useful for the initial registration of the wireless plug-in repeater 100 with the music sharing server system and also for transferring a large volume of data and/or music files. In one embodiment, the digital data port 414 may be a universal serial bus (USB) port. The USB port may be configured to connect with any one of a plurality of USB connector types, including an A-type connector, a B-type connector, a micro-USB connector, a USB Mini-b connector, a USB 3.0 connector, and the like. In another embodiment, data ports other than a USB port may be utilized to provide a wired connection to another electronic device, such as a PC, a computer tablet, and the like.

Referring to FIG. 5, a block diagram of a data processing system 500 is shown that may be implemented as a server within the music sharing server system, or implemented as a personal computer (PC), smartphone, or other computing device coupled to a network 600, as shown in FIG. 6, in accordance with an embodiment of the present invention. The data processing system 500 may be a symmetric multiprocessor (SMP) system including a plurality of processors 502 and 504 connected to system bus 506. Alternatively, a single processor system may be employed. Also, connected to system bus 506 is memory controller/cache 508, which provides an interface to local memory 510. An I/O bus bridge 538 is connected to system bus 506 and provides an interface to I/O bus 512. The memory controller/cache 508 and I/O bus bridge 538 may be integrated as depicted. The processor 502 or 504 in conjunction with memory controller 508 controls what data is stored in memory 510. The processor 502 and/or 504 and memory controller 508 can serve as a data counter for counting the rate of data flow to the memory 510 or from the memory 510 and can also count the total volume of data accessed to or from the memory 510. The processor 502 or 504 can also work in conjunction with any other memory device or storage location.

Peripheral component interconnect (PCI) bus bridge 514 connected to I/O bus 512 provides an interface to PCI local bus 516. A number of modems 518, or wireless cards, may be connected to PCI bus 516. Typical PCI bus implementations will support four PCI expansion slots or add-in connectors. PCI includes, but is not necessarily limited to, PCI-X and PCI Express components. Communications links to the network of computers in FIGS. 1 and 2 may be provided through the modem 518 and network adapter 520 connected to PCI local bus 516 through add-in boards.

Additional PCI bus bridges 522 and 524 provide interfaces for additional PCI buses 526 and 528, from which additional modems or network adapters may be supported. In this manner, the data processing system 500 allows connections to a multiple network of computers. A graphics adapter 530 and hard disk 532 may also be connected to I/O bus 512 as depicted, either directly or indirectly.

Those of ordinary skill in the art will appreciate that the hardware depicted in FIG. 5 may vary. For example, other peripheral devices, such as optical disk drives and the like, also may be used in addition to or in place of the hardware depicted. The depicted example is not meant to imply architectural limitations with respect to the present invention.

The processes explained in detail herein can be embodied in a computer program. Computer programs (also called computer control logic) are stored in memory such as main memory 510, removable storage drive 534, removable media 536, hard disk 532, and signals. Such computer programs, when executed, enable the computer system to perform the features of the present invention as discussed herein. In particular, the computer programs, when executed, cause the processor 502 and/or 504 to perform one or more of the features described herein.

In this document, the terms “computer program medium,” “computer usable medium,” and “computer readable medium” are used to generally refer to media such as main memory 510, removable storage drive 534, removable media 536, hard disk 532, and signals. These computer program products are means for providing software to the computer system. The computer readable medium allows the computer system to read data, instructions, messages or message packets, and other computer readable information from the computer readable medium. The computer readable medium, for example, may include non-volatile memory, such as Floppy, ROM, Flash memory, Disk drive memory, CD-ROM, and other permanent storage. It is useful, for example, for transporting information, such as data and computer/programming instructions, between computer systems. Furthermore, the computer readable medium may comprise computer readable information in a transitory state medium such as a network link and/or a network interface, including a wired or wireless network, which allows a computer to read such computer readable information.

Referring now to FIG. 6, an exemplary embodiment of the network 600 in accordance with the present invention is illustrated in a block diagram. The network 600 includes connections 602 a-n, which are the medium used to provide communications links between various devices and computers connected together within the network 600. The connections 602 a-n may be wired or wireless connections. A few exemplary wired connections are cable, phone line, and fiber optic. Exemplary wireless connections include radio frequency (RF) and infrared radiation (IR) transmission. Many other wired and wireless connections are known in the art and can be used with the present invention.

In the depicted example, the network 600 includes a mobile electronic device 604, a speaker 606, a headset 608, a user computer 610, and a music sharing server system 612, communicatively coupled to the network 600. As will be described further herein, the music sharing server system 612 manages communications between client devices, such as the mobile electronic device 604, the speaker 606, and the headset 608.

In the depicted example, the network 600 can include the Internet 614, which represents a worldwide collection of networks and gateways that use the TCP/IP suite of protocols to communicate with one another. At the heart of the Internet is a backbone of high-speed data communication lines between major nodes or host computers, consisting of thousands of commercial, government, educational and other computer systems that route data and messages. Of course, the network 600 also may be implemented as a number of different types of networks, such as for example, an Intranet, a LAN, a peer-to-peer network, or another WAN. FIG. 6 is intended as an example, and not as an architectural limitation for the present invention.

For convenience, the mobile electronic device 604 will be referred to herein below as a smartphone. However, it should be understood that features of the invention may be carried out using other types of mobile electronic devices, such as, for example, computer tablets, personal digital assistants, music player devices, and the like. The smartphone 604 may be used to play music content. More particularly, the smartphone 604 may include the audio output port 200 (FIG. 2) for communicating an analog audio output signal associated with the music content. In one embodiment, the smartphone 604 is plugged-in to the audio plug 106 of the wireless plug-in repeater 100 a for receiving the analog audio output signal and synchronously sharing the music content associated with the analog audio output signal with remote audio receiver devices (e.g. other mobile electronic devices or audio peripherals, such as headsets and speakers). As used herein, the term “audio receiver device” is intended to indicate any device operable to receive audio signals, whether analog or digital. The smartphone 604 may include one or more of the electronic components described above with reference to FIGS. 4 and 5. For example, in one embodiment, the smartphone 604 may include a user input interface (e.g. touchscreen), a network interface including a cellular network interface, memory, a processor, a display, audio input/output structures, a location detection device (e.g. GPS receiver/transmitter), and one or more sensors (e.g. accelerometer).

The speaker 606 may function to convert an audio analog or digital audio signal into corresponding sound waves. The speaker 606 may be any type of speaker or speaker component, including wired or wireless speakers, computer speakers, portable speakers, floorstanding speakers, a speaker and subwoofer speaker system, stereo speakers, a surround sound speaker system, and the like. In one embodiment, the speaker 606 may include an analog audio port 616 operable to input and/or output analog audio signals. In a further embodiment, the speaker 606 may include an amplifier that amplifies the analog signals to produce amplified sound waves. In another embodiment, the speaker 606 may include a digital input port operable to receive digital audio signals from a peripheral device. In a further embodiment, the speaker 606 may also include a DAC operable to convert the digital audio signals into an analog signal that is used by the speaker 606 to generate sound waves. In one embodiment, the speaker 606 may include a data input/output port, such as, for example, a USB port. In another embodiment, the speaker 606 may include a wireless network interface, such as a Wi-fl network or a Bluetooth network interface so as to be able to connect to other devices wirelessly. In yet a further embodiment, the Wi-fi network may be operable to connect to the music sharing server system 612 wirelessly via the Internet 614. The speaker 606 is shown coupled to the wireless plug-in repeater 100 b. In one embodiment, the wireless plug-in repeater 100 b may be plugged into the analog audio port 616 associated with the speaker 606 for receiving from and/or transmitting audio signals to the speaker 606.

In one embodiment, the speaker 606 transmits analog audio signals through the analog audio port 616 to the wireless plug-in repeater 100 b via the audio plug 106 (FIG. 1) for synchronously sharing the audio content broadcast from the speaker 606 to remote audio receiver devices on the network 600. In a further embodiment, the speaker 606 is a speaker system at a music concert and the wireless plug-in repeater 100 b may be plugged into the analog audio port 616 on the speaker 606 during the concert so as to synchronously share the music content from the concert with remote audio receiver devices (e.g. PC, smartphone, headset, speaker, etc.). These audio receiver devices may be associated with individuals not physically present at the concert. In yet a further embodiment, the wireless plug-in repeater 100 b transmits the music content from the concert in real-time to the music sharing server system 612 over the Internet 614 and the music sharing server system 612 determines what remote audio receiver devices to synchronously share the music content with. In a further embodiment, individuals associated with the remote audio receiver devices are required to provide payment to the music sharing server system 612, or a third-party payment service, in order to receive permissions to synchronously listen to the music content from the concert in real-time, as the concert is taking place.

It is understood that in any communications over a network there may be a propagation delay that represents the amount of time it takes for a signal to travel from a sender to a receiver over the network. In one embodiment, the music sharing server system 612 may permit a propagation delay between the audio content broadcast from the speaker 606 at the music concert (or other audio output device) and the audio content delivered to each of the remote audio receiver devices. Some amount of propagation delay and/or data processing latency (e.g., the music sharing server system 612 identifying music content, verifying permissions to music content, and implementing security protocols, etc.) may be acceptable in some embodiments. For example, in some embodiments, the amount of propagation delay may not be discernable by the human ear. In another embodiment, the amount of propagation delay may be discernable by the human ear, but may be sufficiently minimal so as to be considered acceptable. In another embodiment, the music sharing server system 612 may implement one or more techniques to reduce propagation delay from the original source of the music content to each remote audio receiver device on the network 600. In another embodiment, the music sharing server system 612 may implement one or more techniques to reduce propagation delay, as a result of the propagation delay exceeding a predetermined propagation delay threshold (e.g., 300 ms). As an example, in one embodiment, the music sharing server system 612 may ping each remote audio receiver device and determine an amount of time it takes for each remote audio receiver device to respond to the ping. The amount of time may be considered to represent a delay time associated with the audio receiver device, which may be unique for each remote audio receiver device. Accordingly, the music sharing server system 612 may offset transmission of the audio content according to each estimated delay time so that receipt of the audio content by each of the audio receiver devices may be substantially synchronous with one another. In other embodiments, other propagation delay reduction techniques may be implemented.

In one embodiment, the speaker 606 may operate as an audio receiver device, rather than an audio output device, as described above. The speaker 606 may receive audio signals from the wireless plug-in repeater 100 b, which the speaker 606 uses to produce corresponding sound waves. Stated another way, a remote device communicatively coupled to the Internet 614 may synchronously share audio content with the speaker 606. In one example, the remote device is a smartphone, or other audio output device, that communicates music content over the Internet 614, via, for example, a Wi-fi network, to the music sharing server system 612. The music sharing server system 612 may subsequently, in real-time, transmit the music content to the speaker 606 so as to substantially synchronously share the music content with the speaker 606. As used herein, the term “substantially synchronous” is intended to indicate communicating a continuous time-based communication (e.g., a communication representing a musical composition) from a sender to at least one recipient with minimal delay. It is contemplated that any communications between a sender and a remote recipient will likely have some degree of delay so to not be absolutely or perfectly synchronous. Accordingly, use of the term “synchronous” herein is intended to mean “substantially synchronous,” whether or not the term “substantially” is explicitly used.

The headset 608 can be considered an audio receiver device and may function to convert audio analog or digital signals to corresponding sound waves directed toward a user's ear canal. The headset 608 may also be referred to as “headphones.” The headset 608 may be formed as in-the-ear headphones (e.g., ear buds), on-the-ear headphones, around-the-ear headphones, or any other type of headphone, and may or may not include a microphone. In one embodiment, the headset 608 may be a wired headset, such as, for example, a USB headset. In an alternative embodiment, the headset 608 may be a wireless headset, such as, for example, a Bluetooth headset. In one embodiment, the headset 608 may include a DAC operable to convert digital audio signals to analog audio signals that can be utilized by the headset 608 to produce sound waves. In one embodiment, the headset 608 may be communicatively coupled to a Wi-fi network interface for receiving audio signals over the network 600 during a substantially synchronous music session in accordance with the present invention. For example, in one embodiment, the speaker 606 at the concert may output audio signals to the wireless plug-in repeater 100 b. Subsequently, the wireless plug-in repeater 100 b may communicate the audio signals to the music sharing server system 612. As a result, the music sharing server system 612 may verify that the headset 608 has permission to listen to the audio content from the concert and the music sharing server system 612 may send the audio content to the headset 608 via the Internet 614.

The user computer 610 may function as an initial registration device for registering the wireless plug-in repeater 100 with the music sharing server system 612. The user computer 610 may be a PC, a computer tablet, or other computing device. In one embodiment, the wireless plug-in repeater 100 may store a unique key or alphanumeric code in non-transitory memory. Initial registration may include connecting the wireless plug-in repeater 100 to the user computer 610 so that the unique key can be communicated to the music sharing server system 612 for matching the unique key with a list of authentic repeaters 100 and verifying that the unique key is associated with a unique and authentic wireless plug-in repeater 100. Many users store all or most of their music files on a PC because PCs typically have a relatively large memory capacity, as compared to smaller portable computing devices. Accordingly, in one embodiment, initial registration may include copying music files from the user computer 610 (e.g., a PC) to the music sharing server system 612.

Advantageously, in some embodiments, music files that the user is listening to may be synchronously shared by obtaining the music files directly from the music sharing server system 612. In this embodiment, timing information (e.g., bit number of the song) identifying at what position in the song the user is currently listening to may be communicated to the music sharing server system 612 so that the music sharing server system 612 can begin transmitting the song synchronously to remote audio receiver devices from the same place in the song that the user is currently listening to. For example, a song may be stored as a digital file representing 3 megabits of audio digital data with each bit representing a portion of the song. The user may begin synchronously sharing the song at bit one-million. Accordingly, the wireless plug-in repeater 100 may send to the music sharing server system 612 data identifying bit one-million including data identifying the song and at least one selected audio receiver device. As a result, the music sharing server system 612 may locate the song in a database coupled to the music sharing server system 612 and stream the song beginning at bit one-million of the song to the selected audio receiver device(s). In a further embodiment, the music sharing server system 612 may attempt to account for propagation delay by first pinging the audio receiver device(s). If, for example, an audio receiver device takes 600 milliseconds (ms) to respond to the ping, the music sharing server system 612 may begin transmitting the song to said audio receiver device at bit one-million plus the number of bits equivalent to a 600 ms delay in order to more closely produce substantially synchronous sharing of the song over the network 600.

In another embodiment, instead of the wireless plug-in repeater 100 identifying a position in the song and sending an identification of said position to the music sharing server system 612, the music sharing server system 612 may be responsible for identifying what position in the song the user is currently listening to. For example, the music sharing server system 612 may detect a song associated with the music content that is received, detect where in the song the music content is at, identify a copy of the song stored on a database associated with the music sharing server system 612, and retransmit the music content from the stored copy of the song at the detected time or position in the song. In a further embodiment, the copy of the song is stored as a digital file on the database. In another embodiment, the detected time or position in the song is represented as a timestamp. The timestamp may be considered information identifying the position in the song. In yet another embodiment, detection of the song associated with the music content may be performed by, for example, the music sharing server system 612 comparing the music content to a database of songs to identify a song matching the music content.

Still referring to FIG. 6, the music sharing server system 612 may function as a centralized hub to route, manage, process, and coordinate substantially synchronous sharing of music content across the network 600 in accordance with the present invention. The music sharing server system 612 may include any combination of software applications and/or hardware components for establishing a music sharing and social network-based platform for users. In one embodiment, the music sharing server system 612 is formed as a single server computer. In another embodiment, the music sharing server system 612 includes more than one server computers communicatively coupled to one another across the network 600 (e.g., a cloud computing system). The music sharing server system 612 may include one or more databases for storing music content and associated user permissions, user profile information, audio receiver device information, and the like. The music sharing server system 612 may facilitate interaction and communication among users of client devices (e.g., wireless plug-in repeaters 100 a-n, speakers 606 a-n, headsets 608 a-n, etc.), or with other related applications and/or systems via the network 600. For example, the music sharing server system 612 may provide a platform for users of the client devices who are also members of the social network to, for example, view and access audio receiver devices of other users of client devices who are also members of the same social network for initiating and/or accepting synchronous music sharing sessions with one another. As another example, the music sharing server system 612 may provide a platform for users of the client devices who are also members of the social network to, for example, view and access all or a portion of the music content and music files associated with the user, such as, the music files stored at the music sharing server system 612 associated with the user, and playlists and radio stations associated with third-party music services (e.g., iTunes, Spotify, Pandora, etc.) that the user has an account with. Advantageously, embodiments of the present invention can provide a centralized music depository for music content aggregated from a plurality of third-party music services through a single platform. In one embodiment, the music sharing server system 612 may allow users of the social network to view music content (e.g., name of song, album, artist, category, etc.) that other users designated as friends within the social network are currently listening to on their client devices. Accordingly, users can stay informed about what type of music content their friends are currently listening to and may request synchronous sharing sessions with their friends, if, for example, the song is unfamiliar or otherwise catches the user's interest.

FIGS. 7 a-b illustrate an exemplary process for using the wireless plug-in repeater 100 in accordance with an embodiment of the present invention. Although FIGS. 7 a-b show a specific order of executing the process steps, the order of executing the steps may be changed relative to the order shown in certain embodiments. Also, two or more steps shown in succession may be executed concurrently or with partial concurrence in some embodiments. Certain steps may also be omitted in FIGS. 7 a-b for the sake of brevity. In some embodiments, some or all of the steps included in FIGS. 7 a-b can be combined into a single step.

The process flowchart of FIGS. 7 a-b will be described in conjunction with FIGS. 4 and 6. The process of FIGS. 7 a-b begins at step 700 and moves directly to step 702, where the user couples the wireless plug-in repeater 100 to an initial registration computing device, such as the user computer 610 (e.g., a PC). In one embodiment, the coupling is a wired USB cable connection between the USB port on the wireless plug-in repeater 100 and a USB port on the user computer 610. In another embodiment, the coupling is a wireless connection via a Bluetooth network established between the user computer 610 and the wireless plug-in repeater 100. In a further embodiment, the user computer 610 may be required to pair with the wireless plug-in repeater 100 prior to establishing the Bluetooth network. In one embodiment, a unique key associated with the wireless plug-in repeater 100 is stored in non-volatile memory 404. During the initial registration phase, the unique key may be retrieved from the memory 404 by the processor 402 and, in step 704, uploaded to the music sharing server system 612 over the network 600.

In some embodiments, registration of the wireless plug-in repeater 100 with the music sharing server system 612 may be required to identify unique active wireless plug-in repeaters 100 a-n associated with a user or a user account and/or to verify that the unique active wireless plug-in repeater 100 a-n is an authentic device, rather than, for example, an illegal copy. In one embodiment, the music sharing server system 612 stores the unique key for each known valid wireless plug-in repeater 100 a-n, which it compares to keys that it receives from repeaters 100 a-n that request an initial registration. As used herein, the term “key” is intended to indicate a unique alphanumeric code or any other security feature that may be used to uniquely identify a wireless plug-in repeater to the music sharing server system 612.

In step 706, the music sharing server 612 determines whether the received key matches the any unique keys stored on the server system 612 or a database associated with the server system 612. If the received key matches a unique key stored at the music sharing server system 612 or a database associated with the music sharing server system 612 and the wireless plug-in repeater 100 associated with said unique key has not yet been registered, the music sharing server system 612 may authentic the wireless plug-in repeater 100 and allow it to be registered, in step 708. If the received key does not match a unique key stored at the music sharing server system 612 or an associated database, or if the wireless plug-in repeater 100 associated with the received key has already been registered, the music sharing server system 612 may not allow registration, in step 710. Instead, the server system 612 may send an “authentication failed” message to the requesting wireless plug-in repeater 100 and the process proceeds to step 744, where the process ends.

In step 708, device registration may include the music sharing server system 612 downloading a software application, executable, or other computer instructions to assist the user computer 610 with registering the wireless plug-in repeater 100 and the user. In one embodiment, registration may include guiding the user in creating a user account and/or associating the user account with the wireless plug-in repeater 100. In a further embodiment, the user account may include a user profile with identification and contact information associated with the user. In a further embodiment, the user may be prompted to create a unique user name and password to be associated with the user account. In yet a further embodiment, the user may be able to search, request, and/or add friends to his account. The user may be able to establish settings for permissions associated with said friends. For example, the user may be to allow friends to view audio receiver devices associated with the user's account, select one or more of the audio receives devices, and establish a synchronous music content sharing session with the selected audio receiver devices. In another embodiment, the user may be able to register audio receiver devices with the server system 612 and associate the registered audio receiver devices with the user's account. In yet another embodiment, the user may be able to associate the user's account with one or more third-party accounts for third-party music services, such as, for example, iTunes, Spotify, Pandora, and the like. Advantageously, this may allow the user to access music content from a plurality of third-party music services via one platform, or portal.

From step 708, the process transitions to step 712, where music content files are uploaded to the music sharing server system 612. The music content files may be in any audio file format, such as, for example, MP3, WAV, AIFF, AAC, and the like. In one embodiment, the music content files may be stored on the user computer 610 and accordingly uploaded from the user computer 610 to the server system 612. For example, the music content files may be music files associated with the user's iTunes account, which are typically stored on the user computer 610. As another example, the music content files may be personal music content files, not associated with any music service, such as, for example, musical compositions personally created and/or recorded by the user, or music content files purchased by the user independent of a third-party music service. In another embodiment, the music content files are uploaded to the music sharing server system 612 from a database associated with a third party service, rather than directly from the user computer 610.

After the user completes the registration process, the user may uncouple the wireless plug-in repeater 100 from the user computer 610 and begin normal use. In step 714, the user may couple the wireless plug-in repeater 100 with any audio output device, such as, for example, the mobile electronic device 604, the speaker 606, the headset 608, or any other audio output device operable to output an analog audio signal. For clarity and convenience, the process will be described with reference to the mobile electronic device 604 as the exemplary audio output device; however, it is understood that any audio output device may be connected to the wireless plug-in repeater 100 and that once the analog audio signal is output from the audio output device to the repeater 100, the process may proceed in a similar manner in accordance with embodiments of the present invention. In one embodiment, the user may couple the wireless plug-in repeater 100 to the mobile electronic device 604 by inserting the audio plug 106 into the audio output port 200 (FIG. 2) of the electronic mobile device 604. In another embodiment, the user may couple the wireless plug-in repeater 100 to the mobile electronic device 604 through another wired or wireless connection.

In step 716, the user may log-in to the music sharing server system 612 through a network, such as the Internet 614. In one embodiment, the wireless plug-in repeater 100 may include a software application that the user can interface with via the display 406 and the user input interface 408 of the repeater 100. The software application may provide a user interface displayable on the display 406 that the user can utilize to log-in and otherwise interact with the music sharing server system 612. In one embodiment, the software application may be provided as an app, which is a software application specialized for mobile computing devices (e.g., smartphone, tablet, etc.). In another embodiment, the software application may be provided as one or more web pages within a browser. Web pages are well known in the art and are a resource of information that is suitable for access over the Internet 614 and can be accessed through a web browser running on a computing system, such the wireless plug-in repeater 100. In yet another embodiment, the software application may be implemented as other types of software applications or computer programs. In one embodiment, the user may install and launch the software application on the wireless plug-in repeater 100 that facilitates the log-in with the music sharing server system 612. The user may then use the wireless plug-in repeater 100 to upload a user-identifier with the music sharing server system 612. This user-identifier may include a unique log-in user name or password. This may also include user-identifying information such the user's address, phone number, a photo of the user, biometric data, e.g., retinal/facial scan and fingerprints, and other user-identifying information. As a result of the user providing at least one piece of user-identifying information, the user may be able to access the user account on the music sharing server system 612.

In one embodiment, as part of the log-in process, the wireless plug-in repeater 100 may upload the unique key to the music sharing server system 612. The unique key may be stored in memory 404 on the wireless plug-in repeater 100. The server system 612 may maintain a list of unique keys that are associated with authentic registered wireless plug-in repeaters 100. In another embodiment, this list may also be stored in a database associated with the server system 612. The server system 612 may verify that the unique key uploaded by the wireless plug-in repeater 100 matches a unique key in the list, prior to providing the wireless plug-in repeater 100 with access to the user's account on the music sharing server system 612. In one embodiment, as a result of the user gaining access to the user's account, the user may be able to view all of the playlists, stations, and other music content files associated with the music sharing server system 612, which may include playlists, stations, and music content files associated with third-party music services through the user's third-party music service accounts. These music content files, playlists, and stations may be displayed via the software application interface, as discussed above, with reference to the log-in process in step 716. In another embodiment, the user may also be able to view audio receiver devices associated with the user's account and/or audio receiver devices associated with a friend's user account. In yet another embodiment, the user's “view” of the audio receiver devices may include an icon or other computer displayable indicator along with an identifying name or code associated with the audio receiver device, such as, for example, “My headset” and “Elizabeth's speaker.” In a further embodiment, all audio receiver devices that are viewable and accessible via access to the music sharing server system 612 should first be registered with and authenticated by the music sharing server system 612, as discussed herein above.

In step 718, the user may select music content to be played for the user. In one embodiment, the user may select music content via the mobile electronic device 604, or other audio output device (e.g., speaker or headset). For example, the user may launch a third-party app, such as, for example, Pandora and allow a Pandora radio station to play music on the mobile electronic device 604. As another example, the user may select music files stored on the mobile electronic device 604. In one embodiment, the music content on the mobile electronic device 604 may be converted by a DAC on the mobile electronic device 604 into an analog audio signal. The analog audio signal can then be output via the audio output port 200 (FIG. 2) of the mobile electronic device 604. Accordingly, the music content can be communicated from the mobile electronic device 604 to the wireless plug-in repeater 100 from the audio output port 200 (FIG. 2) of the mobile electronic device 604 to the audio plug 106 of the repeater 100.

In an embodiment where the audio output device is the speaker 606, the user's selection of music content may be whatever audio signals are received into the speaker 606 for producing sound waves. Such audio signals may then be communicated from the speaker 606 to the wireless plug-in repeater 100 via an audio output port of the speaker 606. Likewise, in an embodiment where the audio output device is the headset 608, the user's selection of music content is whatever audio signals are received into the headset 608 for producing sound waves for the user. Such audio signals may be communicated to the wireless plug-in repeater 100 in a manner similar to the speaker 606, i.e., output via an audio output port associated with the headset 608. The audio signals may be digital or analog. If, for example, the headset 608 receives digital audio signals, the headset may include a DAC that converts the digital audio signals into analog audio signals that may then be output via the audio output port and transmitted to the audio plug 106 of the wireless plug-in repeater 100. In one embodiment, the headset 608 may only be operable as an audio receiver device and not as an audio output device.

In another embodiment, the user may select music content to be played for the user via the software application on the wireless plug-in repeater 100. For example, the software application may provide a playlist or other representation of the user's available music content through the music sharing server system 612. The user may then select a song displayed on the display 406 of the wireless plug-in repeater 100 by, for example, clicking on or touching a computer displayable icon, button, or link associated with the song.

In step 720, the process determines whether the user-selected music content was selected through the software application on the wireless plug-in repeater 100, or whether the user-selected music content is from an analog audio signal received through the audio output device plugged-in to the repeater 100, such as the mobile electronic device 604.

If the user-selected music content was selected through the software application on the wireless plug-in repeater 100, the process proceeds to step 722, where the wireless plug-in repeater 100 receives music content from the music sharing server system 612 and plays the music for the user. The music content may be retrieved from the server system 612 over the Internet 614 using the wireless network interface 400 and then played on the wireless plug-in repeater 100 through, for example, the speaker 412, or a headset connected to the USB port 414. In one embodiment, the music content may be received via the wireless network interface 400 as digital data, which may then be converted by the DAC 418 into analog data that is amplified by the amp 410 and output as sound waves to the user via the speaker 412. In another embodiment, the music content may be received via the wireless network interface 400 as digital data, which may then be output as digital data via the USB port 414, where the headset connected to the USB port may include a DAC that converts the digital data into analog data that can be used by the headset to produce sound waves for the user. Communications with the music sharing server system 612 may be implemented via the Wi-fi interface of the wireless network interface 400. Unfortunately, Wi-fi is considered to be less secure than some other wireless and wired networks. Accordingly, in one embodiment, at least a portion of the communications to the music sharing server system 612 are encrypted by the encryption module 420 and at least a portion of the communications received from the music sharing server system 612 are decrypted by the encryption module 420 in order to be utilized by the wireless plug-in repeater 100. In a preferred embodiment, all communications to the music sharing server system 612 are encrypted by the encryption module 420 and all communications received from the music sharing server system 612 are decrypted by the encryption module 420 in order to be utilized by the wireless plug-in repeater 100.

If, on the other hand, the user-selected music content is received from the audio output device plugged-in to the wireless plug-in repeater 100, the process proceeds to step 724, where the wireless plug-in repeater 100 receives analog audio signals from the audio output device, such as the mobile electronic device 604, and plays the audio signal for the user. In one embodiment, the analog audio signals are received via the audio plug 106. The analog audio signals may be amplified by the amp 410 and used by the speaker 412 to produce sound waves for the user. In another embodiment, the analog audio signals are converted by the ADC 418 into digital audio signals, which may then be output as digital audio data via the USB port 414, which may be connected to a USB headset capable of producing sound waves for the user. The present invention envisions that synchronous sharing of music content begins, first with the user playing the music content for himself. Once this step is initiated, the user may synchronously share the music content that he listening to with other people, even other people who are very far away.

In step 726, the user may synchronously share music content by selecting one or more audio receiver devices. In one embodiment, the user may select an audio receiver device via the software application on the wireless plug-in repeater 100, by, for example, clicking on the icon or another computer displayable feature associated with the audio receiver device. In another embodiment, the user may select an audio receiver device by tapping on a touchscreen associated with the display 406 of the wireless plug-in repeater 100. In yet another embodiment, the user may select an audio receiver device through a voice-activated command feature. In a further embodiment, the user may select an audio receiver device through a list of Bluetooth-enabled audio receiver devices that are paired with the wireless plug-in repeater 100.

In one embodiment, the user's selection may be communicated to the music sharing server system 612 over the Internet 614. In another embodiment, the server system 612 may automatically initiate a process for synchronously sharing music content with the selected audio receiver device. In yet another embodiment, the server system 612 may first request permission from the user associated with the selected audio receiver device to receive the music content. The server system 612 may not share music content with the selected audio receiver device until its user accepts the request. In a further embodiment, the server system 612 may send a ping to the audio receiver device over the Internet 614 to determine that the audio receiver device is awake (e.g., power on) and/or for estimating a propagation delay time associated with the audio receiver device.

In step 728, the process may determine whether the selected audio receiver device is within a short range from the wireless plug-in repeater 100 or within a long range from the wireless plug-in repeater 100. If the wireless plug-in repeater 100 is within a short distance from the selected audio receiver device, the process proceeds to step 730, where the wireless plug-in repeater 100 synchronously shares the music content over a short range communications network, such as a PAN. In one embodiment, the PAN may be a Bluetooth network. In another embodiment, the PAN may be an ad hoc Wi-fi network. Propagation delay for communicating the music content over such short distances should be very minimal and may not be discernable to the human ear. Therefore, in one embodiment, propagation delay techniques may not be employed for short range communications. In another embodiment, propagation delay techniques are employed for short range communications. In one embodiment, synchronous sharing of music content with the selected audio receiver device over the PAN may include the wireless plug-in repeater 100 making a copy of the analog audio signal as it is being received via the audio plug 106, the ADC 418 converting the analog audio signal to a digital audio signal, and the wireless network interface 400 transmitting the digital audio signal to the selected audio receiver device over the PAN. This process may be repeated in a continuous manner until, for example, the song is complete or the music content is otherwise interrupted, because the analog audio signals are continuously received via the audio plug 106 as a continuous stream of data. Music content quality may be a function of how quickly and efficiently the processor 402, the ADC 418, and the wireless network interface 400 are able to work together to communicate the analog audio signal from the audio plug 106 to the remote audio receiver device as the analog audio signal continues to stream into the wireless plug-in repeater 100.

If, on the other hand, the wireless plug-in repeater 100 is determined to be within a long range distance from the selected audio receiver device, the process proceeds to step 732, where the wireless plug-in repeater 100 communicates with the music sharing server system 612 over the Internet 614. In one embodiment, the wireless plug-in repeater 100 may consider “long range” communications to be greater than 10 feet. In another embodiment, long range communications may be greater than 20 feet. In yet another embodiment, long range communications may be any communications that exceed the available communications range for any short range communications networks that the wireless plug-in repeater 100 is capable of. In a further embodiment, long range communications may be outside of these ranges.

In one embodiment, the wireless plug-in repeater 100 communicates the music content to the music sharing server system 612 via the Wi-fi interface of the wireless network interface 400. The Wi-fi interface may access the Internet 614 through an access point, such as a Wi-fi router within range of the wireless plug-in repeater 100. In one embodiment, the analog audio signals received via the audio plug 106 are converted into digital audio signals by the ADC 418. In a preferred embodiment, the ADC 418 is operable to convert analog data to digital data at a rate of at least about 192 kHz in order to provide a high quality musical sound. A rate of 192 kHz produces sound quality that is about five times the resolution of a standard music compact disc (CD). The digital audio signals may then be encrypted by the encryption module 420. In one embodiment, the digital audio signals may be triple encrypted by the encryption module 420 for added security. The encryption module 420 may include hardware and/or software components that are operable to implement one or more encryption algorithms. In a preferred embodiment, the processor 402 is a relatively high-speed processor (e.g., 32 MHz processor) so as to be able to convert the analog data to digital data and perform the encryption algorithms quickly enough to continuously process the incoming stream of analog audio data from the audio plug 106, without sacrificing sound clarity and quality. In another embodiment, the ADC 418 and/or the encryption module 420 may be separate from the processor 402, rather than implemented on the processor 402. The encrypted digital audio signals may be communicated to the wireless network interface 400, which may use the Wi-fi interface to communicate the digital audio signals to the music sharing server system 612. The Wi-fi interface may access a Wi-fi router, which then communicates the digital audio signals over the Internet 614 to the music sharing server system 612.

In one embodiment, an identification of the selected audio receiver device and/or a request to share music with the selected audio receiver device is communicated to the server system 612, as well as, the digital audio signals. The identification of the selected audio receiver device and/or the request to share music may also be encrypted by the encryption module 420 prior to being sent over the Internet 614. In another embodiment, the identification of the selected audio receiver device may be the unique key associated with the audio receiver device. In yet another embodiment, an identification of the wireless plug-in repeater 100 and the user (or the user account) is also communicated to the server system 612. The identification of the wireless plug-in repeater 100 and the identification of the user may be encrypted by the encryption module 420 and transmitted to the server system 612 along with the digital audio signals and any other accompanying data. In one embodiment, the identification of the wireless plug-in repeater 100 may be the unique key associated with the repeater 100 and the identification of the user may be, for example, the username or other identifying information. In one embodiment, the music sharing server system 612 may receive the information communicated from the wireless plug-in repeater 100. In one embodiment, the information may include at least one or more of: the digital audio signals associated with a portion of the music content that the user is currently listening to; an identification of the selected audio receiver device; a request to synchronously share music with said audio receiver device; an identification of the wireless plug-in repeater 100 that is submitting the request; and an identification of the user or the user account associated with the wireless plug-in repeater 100. In another embodiment, the information may include additional data.

In one embodiment, the processor 402 may be configured to execute computer instructions that are able to identify music content associated with the digital audio signals. Said computer instructions may also be configured to identify or determine meta data or meta information associated with the music content, such as, for example, an artist's name, album name, track number, a position in the song that is associated with the current digital audio signals being sent, how the music content is formatted (e.g., mono or stereo, 24 bit or 64 bit, etc.), and the like. This meta data may also be communicated to the music sharing server system 612 with the digital audio signals. In one embodiment, the meta data may be used by the server system 612 to identify a digital copy of the song previously stored on the server system 612 and synchronously share the music content from the digital copy on the server system 612, rather than sending the audio signals originating from the audio plug 106. Of course, in an alternative embodiment, the server system 612 may synchronously share the music content with the selected audio receiver device by sending the audio signals originating from the audio plug 106. In this embodiment, meta data may not be required to identify the position in the song because the audio signals are already at the current position in the song. In other words, position information may only be required in an embodiment where the server system 612 elects to share the music content from a digital copy on the server system 612, because the server system 612 will need to identify where in the song the user is currently at and then begin sending the bits at that current position in the song. In step 734, the music sharing server system 612 decrypts the information received from the wireless plug-in repeater 100.

In step 736, the music sharing server system 612 authenticates the request to share the music content being played by the user with the selected audio receiver device. In one embodiment, the music sharing server system 612 determines whether the selected audio receiver device has permission to share music content with the user. This may include verifying that selected audio receiver device is an authentic device that has already been registered with the server system 612. The server system 612 may verify that the unique key matches a unique key stored in the server system 612. In another embodiment, the server system 612 may verify that that the user associated with the selected audio receiver device is friends with the user sending the request to share music content. In yet another embodiment, the server system 612 send a query to the user associated with the selected audio receiver device to verify that the user accepts the request to share music content. In one embodiment, the server system 612 may verify whether the wireless plug-in repeater 100 is an authentic device. This may include verifying that the wireless plug-in repeater 100 has already been registered with the server system 612. The server system 612 may verify that the unique key associated with the wireless plug-in repeater 100 matches a unique key stored in the server system 612. In another embodiment, the music sharing server system 612 may verify that the user who sent the request to share the music content has a valid and active user account with the music sharing server system 612. In yet another embodiment, the music sharing server system 612 may authenticate whether the user has permission to listen to the music content. The music sharing server system 612 may verify that the music content is stored on the server system 612 and that the user possesses a license or other legal permission to listen to the music content. Music content uploaded to the server system 612 during initial registration may also be stored with permission information. For example, music content uploaded from an iTunes account associated with the user may also be identified on the server system 612 as including a license that allows the user to listen to the music content. Accordingly, when the user requests to share the music content with a remote audio receiver device, the server system 612 may first verify that the user has a license to listen to the music content. In one embodiment, if the server system 612 is unable to verify that the user possesses license or other legal permissions to listen to the music content, the server system 612 may deny the user's request to share the music content with another user. One the other hand, if the server system 612 is able to verify that the user possesses a license or other legal permissions to listen to the music content, the server system 612 may accept the user's request to share the music content and may initiate a synchronous music sharing session with the selected audio receiver device.

In step 738, the process determines whether the request to share music content is authenticated. If the request is not authenticated, the process proceeds to step 740, where the authentication has failed. From step 740, the process proceeds to step 744, where the process ends. On the other hand, if the request is authenticated, the process proceeds to step 742, where the music sharing server system 612 synchronously communicates the music content to the selected audio receiver device over the network 600, as discussed herein. An exemplary process in accordance with the present invention is shown in FIGS. 7 a-b. The process ends at step 744.

A device, system, and method has been disclosed that that allows audio content from a single audio source, e.g., a cellular mobile device, a speaker, or a headset, to be simultaneously, synchronously communicated, over long distances, to a multitude of remote audio receiver devices, in a secure manner, while maintaining high sound quality.
